About The Position

As a Geologist, you will help build the orebody knowledge that supports future mining decisions at the Resolution Copper project near Superior, Arizona. You will work across surface and underground environments to collect, validate, and interpret geological, geotechnical, and drilling data, collaborating with drilling, core handling, modeling, geotechnical, and contractor teams. The role offers hands-on experience across the resource evaluation workflow, from drilling and core logging to modeling and interpretation, with support from the Resource Evaluation leadership team. Daily work may include managing core inflows, logging and quality-checking data, coordinating or supervising drilling activities, and completing underground mapping, scanning, and sampling. You will interpret drill core, core-scanning outputs, and downhole geophysical data, communicate geological interpretations, maintain databases and reports, and contribute to technical projects that improve understanding of structure, alteration, and mineralization. Underground work and rotating or night shifts may be required. Relocation assistance is available to eligible candidates selected for the role.
